Hi there! Thanks for replying me, by the time you did that I already had a card coming to me and by now I successfully installed it.
If you go with a 6800xt you should definitely replace your PSU, yes.
450W isn’t enough for RDNA2.
bootarg stays the same, yap.
I have read that some of the folks had luck with 450w PSU and 6800XT, but decided to spent a bit more( ~ 200 USD) for a decent 750 PSU from Corsair.
here they are right before the installation:
Fitting it was a challenge, but apparently that was the hardest part, because I did nothing in order to make it work, it just did from the first try:
Here are my Geekbench and Unigine Heaven Benchmark scores:
So I guess they aren't bad. Also gaming under Windows had a significant boost as well, but my priority was FCP performance first, due the fact that 8gb in 5700xt was quite often not enough for 4k timeline with variety of heavy VFX, so I had to create a separate project in order to render few seconds of some heavy effects, export them and use on a main timeline as a prores clip. making changes that way is...long. Now I don't need to do that.
Replacing your CPU shouldn't be a problem. It might occur that speedstepping wouldn't work as expected because an i7 8700 matches the iMac19,1 sysdef more closely (assuming you're using that for your rig). If you don‘t plan to overclock, choose the non-k version - there‘s no considerable
performance increase to expect
I've made a decision to postpone this purchase, especially since it won't make huge difference in my current workflow, unlike upgrade of the GPU did. But thanks again!
In general, I believe that it might be a good idea to update to F14 BIOS at some point especially concerning the
Resizable-BAR
Looks interesting and promising, but I prefer to play safe with my editing rig, so I'll wait for more feedback on this.
Overall my only thought about further enhancing the user experience with this hackintosh is probably trying to change iMac 19,1 to iMacPro 1,1 and see what can I gain with that.
I don't really use SideCar these days, and believe once I switch to iMacPro 1,1 will loose that ability, but I will have even bigger boost in GPU performance, not sure whether it will be better than 6800xt + QuickSync though.
Since I have a second backup SSD will try there first, will post the results here. In theory I only will have to disable the Intel graphics in BIOS and generate new SMBIOS.
